HASHBYTES is the best for determining total and complete uniqueness if you are willing to deal with the overhead.

From MSDN:

Return Value
varbinary (maximum 8000 bytes)

If I'm going to possibly compare 8000 bytes I'm usually better off just doing the column compare, thus why I rarely use HASHBYTES.

I've never had HASHBYTES return more than 14 bytes.
